Abstract (en)
[origin: US5576198A] Novel compositions and methods useful for genetic engineering of plant cells to provide a method of controlling the timing or tissue pattern of expression of foreign DNA sequences inserted into the plant plastid genome are provided in the instant invention. Constructs include those for nuclear transformation which provide for expression of a viral single subunit RNA polymerase in plant cell tissues, and targeting of the expressed polymerase protein into the plant cell plastids. In addition, plastid expression constructs comprising a viral gene promoter region which is specific to the RNA polymerase expressed from the nuclear expression constructs described above, and a DNA sequence of interest to be expressed in the transformed plastid cells are provided. Plant cells and plants comprising the nuclear and/or plastid constructs described herein are of interest. Of particular interest is a method of controlling expression of the inserted plastid gene constructs in a tissue and/or developmental specific manner in plants comprising both the nuclear polymerase construct and the plastid expression constructs.
